空间信息的结构、表达及其理解机制

Structure, Representation and Understanding of Spatial Information

在分析传统地理信息系统理论主要缺陷的基础上，将语言学引入地理信息系统，提出了数字环境下空间信息结构与表达的认识模型——空间信息的语言学模型，探讨了空间信息的语言学特征，主要是语言单位、语法及语义机制，并就其对地理信息系统各环节特别是空间信息的智能化数据处理所产生的影响进行了讨论。

Spatial information is another form of information in contrast with text information represented with natural language. The interior structure, representation and understanding mechanism are the prerequisites to realize the capturing, managing and processing of spatial information. As many years passed, GIS has succeeded as a technology of engineering, especially in the field of data management and non intelligent data processing. However, it is generally accepted that the further progress of GIS depends on the more concern with the spatial information itself. In this paper, based on the drawback analysis of traditional GIS theory, linguistics is introduced into GIS. The understanding paradigm of the structure and representation of spatial information in digital context, i.e. linguistic paradigm of spatial information is proposed. The linguistic characteristics of spatial data in terms of language unit, syntax and semantics are discussed, along with the influence on the aspects of GIS with special care about the intelligent data processing.
